Active Headrest

ACTIVE HEADREST







In case of rear-end collision, the headrest moves forward to immediately support the passenger's head to reduce the possibility of injury to the neck.
1. In case of rear-end collision, the passenger's body will move rearward by the impact.
2. When the body moves rearward, the thrust receiving plate inside the seat is pressed in.
3. When the thrust receiving plate is pressed in, the headrest moves forward due to a levering action.
